Several major studies, published today, concur that virtually all current global human populations stem from a single wave of expansion out of Africa. Yet one has found 2% of the genome in Papuan populations points to an earlier, separate dispersal event – and an extinct lineage that made it to the islands of Southeast Asia […]

Did archaic genetic variants help Melanesians adapt?

Compared with other world groups, the DNA of Melanesian populations carries some of the largest percentage of ancestry from now-extinct Neanderthals and Denisovans. A genomic study of Melanesians suggests that certain genetic variants inherited from archaic […]
